sides more rounded, so that their form is ovate and not 

 in the least oblong-quadrate. The white tomentose border 

 covers the two marginal interstices and behind reaches the 

 suture; it also nearly reaches the base and at its termina- 

 tion is separated from the humeral spot only by the extre- 

 mely narrow carina into which the 7th interstice is here 

 contracted. 



The description of A. Actceon (Erichs.) also from Ben- 

 guella , agrees very nearly with A. ooptera , but no men- 

 tion is made of the white humeral spot, and besides the 

 »interstitiis leviter convexis" and » striis postice evanescen- 

 tibus" do not at all fit but suit almost exactly examples 

 of A. cinctipennis (Lequien) which I have examined from 

 Lake Ngami and Damaraland. 



Ant hi a niveicincta, nov. spec. 



A. omostigma 1 (Chaud.) proxime affinis. Nigra, thorace 

 utriuque vitta vel macula elongata, elytris margine lato 

 (antice angustato humeros baud attingenti) albo-pubescen- 

 tibus : capite thoraceque sparsissime punctulatis : elytris elon- 

 gato-ovatis, prgecipue basi et apud humeros alte convexis, 

 punctulato-striatis , interstitiis convexis , singulis utrinque 

 setifero-punctatis. 



cf minor. Thorax anguste cordatus , lateribus pone me- 

 dium sinuatis deinde gradatim convergentibns , disco utrin- 

 que longitudinaliter convexo loboque brevi obtuso apice 

 medio emarginato et utrinque sinuato-truncato. — Long. 

 37 millim. 



9- Elytra latius elongato-ovata , thoraceque sicut in cf 

 sed basi obtuse convexo. — Long. 42 millim. 



A male from Humpata (Veth & v. d. Keilen), and a 

 female from Mossamedes (Sala). 



Extremely near A. omostigma from Benguella; differing 

 only in the absence of the white pubescent humeral spot 

 and in the stronger convexity of the elytra at the base and 

 shoulders ; the elytra although equally elongated are espe-
